BOBBlN-WINDER.

SPECIFICATION forming part of Letters Patent No. 329,144, dated October 27, 1885.

Application filed October 20, 1884. Serial No. 145,942.

To all whom it may concern:

Be it' known that I, ABRAHAM CoATEs, of Watertown, in the county of Jefferson, in the State of New York, have invented a new and useful Improvement in BobbinWVinders, of which the following is a specification, reference being had to the annexed drawings, in which- Y Figure l is a perspective View, and Fig. 2 a transverse section. Fig.3 is a transverse section showing interchangeable wormwheels.

The object of my invention is to provide a simple and efficient bobbin-Winder capable of winding t-hreads of all sizes evenly upon the bobbin.

It consists in the combination, with the spindle of the bobbin-Winder, of worm-wheel gearing and a cam operated thereby,- va lever moved by the said cam, and carrying a threadguide, through which the thread passes to the bobbin.

In ordinary bobbin-winders the adjustment is fixed and unalterable for a given size of thread. In my improvement I have provided for winding different sizes of thread by interchangeable worm-wheels, anda spring adjustment for the worm-wheel shaft, by means of which wormwheels of various sizes may be brought into engagement with the worm upon the bobbin-Winder spindle.

In one of the arms, a, of aforked frame,A, adapted to be pivoted on the table of a sewing-machine or other machine in connection with which a bobbin is used, is journaled a Spindle, B, carrying at the outer end a friction-wheel, (l, by which it takes the motion, and at the inner end a worm, D. The other arm, d, of the frame A is provided with the usual spring-acted bobbin-holder, E, between which and the concave end of the spindle B the bobbin F is held.

A shaft, G, is journaled between ears projecting upward from the frame A, and carries acam, H, for actuating the thread-guide I, and is provided with a worm-wheel, J engaged by a worm, K, on the shaft L. At a point immediately above the center of the shaft G the shaft L is provided with a hemispherical cavity, b, for receiving the spherical end of the screw c, upon which that end of the shaft revolves. The opposite end of (No model.)

the shaft L is received in a bracket, d, which is pivoted to a sliding spring-acted bar, e, moving in bearings in the frame A at right angles to the spindle B. The shaft L is prolonged beyond the bracket d for receiving wormwvheels M, adapted to be engaged by shaft L, which swings on the spherical end of the screw c, and presses the worm-wheel M into engagement with the worm D on the spindle B, and whatever the size of the wormwheel M the spring h is sufficient to always keep it in engagement with the worm D. The screw c passes through a nut, z', which slides in bearings in a post, j, projecting upward from the frame A. A spring, 7c, placed above the nut t' presses the said nut downward and insures the engagement of the worm K with the worm-wheel J. The worm Kbeing pressed downward into engagement with the wormwheel J in the manner described, and the worm-wheel M being pressed upward into engagement with the worm D,insures a positive communication of motion from the spindle B to the shaft G, so that no loss of motion or irregularity in the rotation of the shalt G can occur.

An arm, N, pivoted to the frame A, and extending under the shaft G toward the bobbin F, supports upon its upper side a stud, Z, which carries a roller, m, bearing on the edge of the cam H. The roller m is kept in constant contact with the edge of the cam H by a spring, n, attached to the frame A,and bearing against the pivoted arm N near its center of motion, and pressing the arm N and roller m toward the cam H. The cam H is formed of a section of a hollow cylinder, and is adapted to impart to the arm N a uniform reciprocating motion, carrying the thread-guide I,which is secured to the free end of the said arm, back and forth before the bobbin F. The thread to be wound upon the bobbin F passes through a slit, o, in the thread-guide I before being delivered to the bobbin, so that when the IOO worm-wheel M, adapted to the thread to be wound upon the bobbin, is placed on theshaft L, the thread-guide will carry the thread along the length of the bobbin F, so that it will be wound in uniform spiral layers.

Wormwheels M of various sizes, adapted to the different sizes of thread,will be supplied with the bobbin-winder, and may be marked, so that the user of the Winder may know what worm-wheel to use for the given size of thread.

The advantage secured by my improvement is the uniform winding of the thread upon the bobbin in successive layers, enabling a greater amount of thread to be wound upon the bobbin and avoiding the kinks in thread due to irregular winding.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a bobbin-Winder, the combination,

vwith the thread-guide-actuating cam, of a lbobbin-winder spindle, a worm on the bobbinwinder spindle, and means for securing the bobbin in operative position, an adjustable shaft intermediate between the bobbin-Winder spindle and shaft of lthe threadguide-actuating cam, and interchangeable worm-wheels adapted to be carried by the intermediate shaft and be engaged by the worm on the bobbin-winder spindle, substantially as and for the purpose specified.

2. The combination,in a bobbin-Winder, of the spi'ndle B, and means for securing the bobbin in operative position, the worm D, worm-wheel M, shaft L, worm K, worin-Wheel J, shaft G, thread-guide I, and spring-acted lever N, substantially as herein specified.

3. In a bobbin-Winder, the combination, with the spindle B, and means for securing the bobbin in operative position, the threadguide I, and intermediate parts, of the intermediate shaft, L, and spring-supported bearings at opposite ends thereof, adapted to press the Worm K and worm -wheel M against the partswith which they engage, as herein specified.

4. In a bobbin-Winder provided with the spindle B, and means for holding the bobbin in an operative position, the combination, with the shaft L, mounted in a pivoted bracket, and adapted to receive interchangeable worm-wheels of different sizes, of the spring h, for'pressing the shaft L toward the spindle B, to bring the worm-wheel M into engagement with the worm-wheel D on the spindle, as specified.

5. In a bobbin-Winder provided with a spindle, B, and bobbin-holder E, the combination, with the shaft L, mounted in a pivoted bracket provided with a hemispherical cavity, b, in the end thereof, of a spherical bearing iitted to the hemispherical step to allow of the rotation and swinging of the shaft L, as
